In the studio, how to match the size of aperture and shutter and how to look better? !

It is recommended to learn the most basic concepts of photography, such as aperture and shutter. If you don't understand, you can read the instructions clearly. A large aperture will blur and increase the luminous flux. Use a large aperture when shooting people or in poor light. Small aperture can increase sharpness and reduce chromatic aberration, but it will reduce luminous flux. The best aperture of a general lens is to reduce the maximum aperture by 2 or 3 steps. If the aperture is reduced to a small size, it will glow when you shoot the light at night, but if it is reduced too small, the picture quality will also decline. High-speed shutter can solidify high-speed moving objects and reduce exposure, while low-speed shutter can display the trajectory of objects and increase exposure. The safety shutter is below 1/60, and the anti-shake can be below 1/30. If the telephoto lens does not turn on anti-shake, the safety shutter is at 1/ focal length, which is lower than the safety shutter. It's easy to shake the photo and blur it. This is about the focal length. Aperture and shutter are the combination that determines exposure. There is an exposure meter in the camera, which can increase or decrease the exposure according to the photometric results. If the contrast between light and dark is obvious, use spot metering mode. Digital cameras also have sensitivity, that is, ISO, to control exposure. ISO should not be too high, otherwise the picture will be blurred.
